Forty eight needle biopsies of the liver, from children registered in the histopathological laboratory of Jos University Teaching Hospital (JUTH) were reviewed. Liver disease diagnosis was based on histopathological criteria without recourse to either clinical, biochemical or microbiological data. Hepatic Schistosomiasis (37.5%) and liver cirrhosis (25%) were the most frequently diagnosed lesions. There were only two cases of biliary cirrhosis secondary to biliary atrisia. Parasitic infestation of the liver was the most common cause of childhood hepatic dysfunction. Our results confirm the observations of workers in other tropical and subtropical regions, where infection is the commonest cause of childhood liver disease. This is in sharp contrast to the findings from European countries where neonatal hepatitis or biliary atresia are the most commonly diagnosed disorders. This retrospective study provides a good starting point for a prospective study, to determine the incidence and severity of childhood liver disease in Nigeria. This is a retrospective histopathological study aimed at establishing the pattern of liver disease in the paediatric age group in Jos. The indication for liver biopsy in all the cases was hepatosplenomegaly with or without biochemical abnormality.

Mansonic schistosomiasis is an endemic disease in Brazil, with an estimated 10-12 million people infested. Among its clinical manifestations, the hepatosplenic form causes portal hypertension which, in turn, brings about severe digestive hemorrhage, the most serious complication of the disease. Normally, the patients are young, and have hepatosplenomegaly, hypersplenism without clinical manifestations, and slightly reduced hepatic function. The angiographic findings are characteristic, differing from those of hepatic cirrhosis. In Brazil, the definitive treatment for gastrointestinal hemorrhage is surgery, which should be done under elective conditions whenever possible. During a short period of time, known as the "risk period" (the time between the hemorrhagic episode and the surgery), propranolol has been used to prevent further bleeding. Surgical treatment is indicated only after the first episode, and never on a prophylactic basis. In 1977, a prospective, randomized trial was begun in order to assess the delayed results of the 3 surgical operations most widely used in this country. The study was interrupted after 94 patients had been operated on due to the high incidence of encephalopathy in the group who underwent classical splenorenal shunt. After a follow-up of at least 60 months and, at most, 130 months, the results showed that classical splenorenal shunt caused encephalopathy in 39.3% of the cases and distal splenorenal shunt in 14.8%. None of those submitted to esophagogastric devascularization with splenectomy developed encephalopathy. The 3 procedures showed similar rates of hemorrhagic recurrence.

A woman with known Niemann-Pick disease, type B, presented at age 33 with upper gastrointestinal bleeding, ascites, and peripheral edema. Evaluation showed massive hepatosplenomegaly, infiltration of the liver with Niemann-Pick cells, cirrhosis, and evidence of portal hypertension. Chronic gastrointestinal bleeding, thrombocyctopenia, and platelet dysfunction were treated successfully by splenectomy. Cirrhosis and portal hypertension have not been reported previously in adult Niemann-Pick disease in the absence of some other cause.

Essential mixed cryoglobulinemia (EMC) is a syndrome characterized by cryoglobulinemia and clinical features including purpura, arthralgia, asthenia (Meltzer-Franklin syndrome) without evidence of any systemic disease Liver involvement in the course of EMC is described in 50-84% of patients. It consists of mild silent hepatosplenomegaly and slightly rise of serum amino transferase. Eleven patients with clinical and laboratory findings suggestive for EMC (five type II and six type III) underwent percutaneous liver biopsy to evaluate the degree of liver involvement. Two liver cirrhosis, two chronic active hepatitis, one chronic persistent hepatitis and a case of hepatic steatosis were found. A type III cryoglobulinemia was present in four of the six patients with liver involvement. All the patients were Hbs Ag negative but three of them were Hbs Ab positive. The pathogenesis of liver involvement in the course of EMC is still now uncertain. The authors believe that a previous HBV infection plays no role in the pathogenesis of EMC syndrome. This syndrome must be considered different from mixed cryoglobulinemia secondary to chronic liver disease. They suggest that liver biopsy is mandatory during the course of EMC even when clinical and laboratory data are silent.

Seventy eight patients with diffuse hepatic lesions were selected for this study. They were classified after liver biopsy histopathologically into four groups. 45 patients with pure bilharzial hepatomegaly (group 1). 12 patients with mixed bilharzial hepatosplenomegaly with hepatitis (group 2). 16 patients with chronic active hepatitis and cirrhosis (group 3) and 5 patients with extrahepatic cholestasis (group 4). Ultrasonography of gall bladder was done for all patients. Group 3 patients showed the highest incidence of gall stones (29.4%) as compared to other groups (P less than 0.05).

Circulating immune complexes (CIC), adult schistosome antibody, and total immunoglobulin concentrations were estimated in sera from 35 chronic Schistosoma mansoni patients with different infection intensities and different pathological complications. High CIC levels were present in about one-third (10/35) of the sera. Most of the patients (9/10) with elevated CIC levels also had hepatomegaly or hepatosplenomegaly. This finding is significant in the pathogenesis of schistosomal liver fibrosis and may also apply to other liver diseases, especially cirrhosis. No correlation was found between infection intensity as judged by stool egg counts and CIC levels. A reverse relationship was observed between the level of anti-adult worm IgG and CIC levels. CIC levels were elevated within 7 and 28 days after treatment in most patients. Hypergammaglobulinaemia was detected in most sera.

The quantification of liver function is possible using the approach of salivary caffeine clearance. Hepatopathy sometimes complicates cystic fibrosis (CF), thus suggesting the use of this diagnostic tool in CF as well. Since in CF some compounds are poorly absorbed or abnormally metabolized, and the function of salivary glands or renal tubuli partly impaired, caffeine was measured in urine, blood, and saliva after a single oral dose of 3 mg/kg in CF patients. The urinary excretion rate of caffeine was normal in five CF patients. The caffeine levels in plasma or saliva, measured 4 to 5 h and 16 to 17 h after caffeine intake, were normal in 34 nonhepatopatic CF patients. The calculated salivary caffeine clearance was comparable in the 34 nonhepatopatic CF patients (1.88 +/- 0.46 ml/min/kg) and in the control group (1.88 +/- 0.44 ml/min/kg). In CF patients, no correlation was found between caffeine clearance and body weight, height, relative underweight, dosage of pancreatic enzymes, or Chrispin-Norman x-ray score. The salivary caffeine clearance was reduced in seven hepatopathic CF patients (1.32 +/- 0.63 ml/min/kg, p less than 0.01); nevertheless, the salivary caffeine clearance was reduced (boundary line at 1.1 ml/min/kg) in three CF patients with proven liver cirrhosis but not in four with hepatosplenomegaly and altered liver tests. These data indicate an unaltered caffeine metabolism in CF and open the way for the use of this diagnostic procedure in CF as well. This test might be valuable in CF patients with clinical or laboratory findings suggesting liver involvement.

A case of a patient with clinical picture of hepatosplenomegaly, portal hypertension, dilatation of hepatic veins and inferior vena cava, without venous thrombosis or other causes of obstruction of right-sided heart, is described. This picture is compatible with the Budd-Chiari syndrome. Echocardiography has shown a hypertrophic cardiomyopathy causing relevant dilatation of both atria and it has allowed us to exclude the presence of a constrictive pericarditis. The hypertrophic cardiomyopathy is first considered as a cardiac cause of cirrhosis mimicking the Budd-Chiari syndrome.

Liver cirrhosis was induced in rats by the combined action of oral phenobarbitone and inhalations of carbon tetrachloride vapors. These rats manifested hepatosplenomegaly, hypoalbuminemia, and 2- to 17-fold elevations in serum transaminases and alkaline phosphatase levels. The hepatic antioxidant enzymes, superoxide dismutase and catalase, showed 28 and 60% decreases, respectively. There was, however, no increase in the hepatic lipid peroxidation. These studies suggest that in cirrhosis liver cell damage may result due to the direct attack of the oxygen free radicals. Lipid peroxidation in the liver may not be a prerequisite for the development of cirrhosis, as is generally believed.

Subchronic and chronic toxicities of hexachlorobenzene (HCB) were studied in both sexes of Swiss mice, Syrian golden hamsters and Sprague-Dawley rats, at dietary dosages of 0, 100 and 200 ppm (mice), and 0, 200 and 400 ppm (hamsters and rats) for 90 days. At day 91, 25/50 animals in each of 18 groups were killed for histology studies. The rest were killed at 6-week intervals until the study was ended. Marked hepatosplenomegaly, enlarged thymuses and lymph nodes, or swollen and granular-looking renal cortices with depressions or nodulary areas were commonly observed. Dose- and sex-dependent progressive changes included toxic-degenerative hepatitis, chronic cirrhosis, hepatomas, bile-duct adenomas and a few hepatocarcinomas in older animals. A generalized lymphohaematopoietic response led to thymic, splenic and nodal lymphosarcomas, especially in female mice. Toxic-tubular nephritis with cortical infarcts developed into regenerative foci and renal adenomas in low incidences. Liver lesions were more prominent in females, while renal changes were most common in male rats. HCB was retested in both sexes of rats at oral doses of 0, 75 and 150 ppm for up to 2 years. At the start, each group contained 94 rats, and four randomly selected rats were killed at weeks 0, 1, 2, 3, 4, 8, 16, 32, 48 and 64 for microscopy. Progressive liver lesions started as hyperaemia and degenerations (4 weeks), and developed into toxic hepatitis, cirrhosis and formation of pre- and neoplastic foci (36 weeks), with hepatomas, bile-duct adenomas and hepatocellular carcinomas (64 weeks) in very high incidences in females and renal adenomas in male rats.
